Rollup merge of #105484 - nbdd0121:upcast, r=compiler-errors
Implement allow-by-default `multiple_supertrait_upcastable` lint

The lint detects when an object-safe trait has multiple supertraits.

Enabled in libcore and liballoc as they are low-level enough that many embedded programs will use them.
